This is a Scrum tool, and there are so many fields on a Task and Story that are very necessary but are related to field relationships. Having the ability to associate logic relationships between fields would either give an error preventing the issue ro warn about the issue.

Here are examples of field relationships:
* A Sprint date range must be within the Project date range.
* A Story cannot be Completed (for example, Done, or Accepted) unless all Tasks are Completed.
* A Story must have an assigned Team before it can be assisgned to a Sprint

Obviously these relationships would need to be configurable.
